大海雀（学名：Pinguinus impennis），又称大海燕，因外表和企鹅相似而有时又被称作北极大企鹅，是一种不会飞的鸟，曾广泛存在于大西洋周边的各个岛屿上，但由于人类的大量捕杀而在19世纪灭绝。大海雀是大海雀属唯一的现代物种。从前，大海雀属包括另外一种不会飞的巨型海雀，它们分布于大西洋地区。大海雀在多岩石孤岛繁殖。大海雀们能很容易地从这些孤岛到海洋并获取充足食物。但实际上，只有少数的大海雀能拥有这种稀少的繁殖地。繁殖期过后，大海雀在北大西洋中觅食。范围南至西班牙北部，北达加拿大、 格陵兰岛、冰岛、法罗群岛、挪威、爱尔兰和英国。

The great auk (Pinguinus impennis) was a flightless bird of the alcid family that became extinct in the mid-19th century. It was the only modern species in the genus Pinguinus (unrelated to penguins, although it was the first bird to be called penguin). It bred on rocky, isolated islands with easy access to the ocean and a plentiful food supply, a rarity in nature that provided only a few breeding sites for the auks. When not breeding, the auks spent their time foraging in the waters of the North Atlantic, ranging as far south as northern Spain and also around the coast of Canada, Greenland, Iceland, the Faroe Islands, Norway, Ireland, and Great Britain.
